When I run the sqls in SQL Server Management Studio, below errors occur:
Warning: A domain error occurred.
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.

When I try similar thing with OracleClient, exception throws when executing reader:
ORA-01428: argument '10290' is out of range

The error message is same as directly execute the sql on Oracle:
SELECT t0."CustomerID", t0."OrderDate", t0."OrderID"
FROM "Orders" t0
WHERE (ACOS(t0."OrderID") = 0.0)

For both Sql server and Oracle, exception is expected, because acos arguments should be -1 to 1.

So my question is, is it a SqlClient bug, or there is any secret in IQToolkit?
